Complexity lab / SAT diagonalization

P != NP as a question of compression, witness space, and self-reference.

This room reconstructs the uploaded preprint series as an academic working model: a proposed proof route through SAT solution-space incompressibility, not a claim of settled community acceptance.

Independent preprint Expert review required Six uploaded PDFs
assume f phi_f exclude f(enc(phi_f)) SAT remains?

Problem

P vs NP frame

If SAT is solvable in polynomial time, then P = NP; if no such polynomial-time procedure exists, P != NP.

Formal object P = NP iff SAT in P
Function in argument

Sets the target problem through the standard Cook-Levin equivalence.

standard background

Interactive instrument

Compress a witness space, then watch the diagonal formula avoid it.

This finite model demonstrates the mechanism behind the uploaded papers: a small candidate list is selected, the formula adds one exclusion clause per candidate, and the remaining Boolean cube is inspected for witnesses. It visualizes the diagonal exclusion step; the full preprint additionally requires the fixed-point, constructivity, and barrier arguments.

Mode toy verifier Shows the construction logic; it is not a substitute for the full proof.
Boolean cube 16 assignments
Remaining witnesses 11

Generated formula

phi_f excludes exactly the candidate set.

Candidate set 5
Exclusion clauses 5
Diagonal result SAT

The compressor selected five assignments. The generated CNF forbids those five points and leaves other assignments available as witnesses.

f candidate excluded by phi_f remaining satisfying witness first available witness

Review cockpit

A world-class version must expose the proof obligations, not hide them.

Selected audit node 01

Compressibility equivalence

What this page demonstrates

The page models a compressor as a finite candidate selector over {0,1}^n.

What the PDF must prove

Prove the precise equivalence between a polynomial hitting-set compressor for SAT witnesses and a polynomial-time SAT decision/search procedure.

Failure mode to rule out

If CH is weaker or stronger than P = NP, the diagonal contradiction may miss the target theorem.

Proof obligations

The site should make the argument inspectable, not merely impressive.

The strongest version of this page is a verification cockpit: every major claim becomes a node, every node has a formula, and every formula has an audit question.

  1. CH equivalence to P = NP is stated with an explicit candidate-set function.
  2. phi_f must be constructible within polynomial bounds for every admissible f.
  3. The exclusion clauses must forbid f's candidates without destroying satisfiability.
  4. The satisfiability margin must survive encoding overhead and boundary cases.
  5. The argument must not be a disguised relativizing, naturalizing, or algebrizing method.
  6. Empirical checks should be treated as reproducibility evidence, not as final proof.

Barrier audit

Relativization, natural proofs, and algebrization are displayed as active tests.

Relativization

Many diagonal arguments fail because they would also work relative to arbitrary oracles.

The preprint series argues that the construction is index-sensitive and tied to canonical encodings. Does the construction depend on non-oracle-stable syntactic information in an essential way?

Natural proofs

Large, constructive properties of Boolean functions cannot easily prove strong lower bounds under standard cryptographic assumptions.

The measure-growth predicate is presented as not large, not distribution-robust, and not merely a property of the Boolean function. Is the predicate genuinely non-natural under the Razborov-Rudich criteria?

Algebrization

Some non-relativizing techniques still fail after algebraic extension.

The work argues that clause-level exclusion and witness uniqueness collapse under low-degree algebraic transfer. Can the core invariant be preserved in an algebraic extension, or does it necessarily break?
